A new update for Maps on Windows Phone 8 has been spotted in the wild, and it supposedly improves the quality of, well, maps -- including those downloaded for offline use. There's no push mechanism for getting this refresh, though, so those with a WP8 device will want to check for it via the Settings menu. What's changed, exactly? According to WMPoweruser, maps have improved detail and traffic info. If you've downloaded the update, tell us about it in the comments below.
